Geologist reconverted in computer science, I have been passionate about Paleontology and Mineralogy for more than 45 years, spent mainly in the field. I have been a full time crystal maker for 3 years and I mainly offer pieces from my own harvests in the Oisans, Mont Blanc and South East of France.
